Is that real? If so, is it just due to that card only being in the PW set? Is it actually going to be playable?
Because Wizards made sure to say those sets would be objectively bad. I want to think that they could go at least one set before failing that standard.
The exclusive cards from that set are either high or worthless. I would not trust any prices from those planeswalker decks.
In general Preordering is bad because most cards drop in price and never get back to their preorder price. However, there are cards that do go up and there is something to be said about being able to have the cards on day one. Consider it paying a premium to get the cards now rather than waiting. Is the time spent waiting for the cards to drop worth the extra money you spend to have the cards? If so, get the cards. If not, then wait.
